Customer Ratings & Reviews

Hi JamesB,

Thank you for sharing your experience with Wi-Fi connectivity. If your TV is having trouble connecting to the network, the following steps may help resolve the issue:

Signal & Setup Tips:
1. Check TV-to-router distance – Your TV should be within 50 feet of the modem or access point for reliable signal strength.
2. Minimize interference – Turn off nearby wireless devices and make sure there are no physical barriers (stone walls, fireplaces, appliances) between the TV and router.
Power Cycle Devices:
3. Restart both your TV and router – Unplug both devices for at least 30 seconds, then plug them back in and allow them to reboot fully.
Connection Type:
4. Evaluate your connection method –
o If using Wi-Fi, move your router closer to the TV and eliminate any obstructions.
o For a more stable connection, we strongly recommend using a wired Ethernet cable.
o If already using Ethernet, verify the cable is working by testing it with another device.

Hi AnthonyB,

I'm sorry to hear you're experiencing audio delay issues when pairing Bluetooth devices with your U7900 TV. Before using Bluetooth, please keep in mind the following:

1. Bluetooth devices and Wi-Fi Speaker Surround Setup cannot be used at the same time.
2. Compatibility issues may occur depending on the Bluetooth device - for example, some mobile-exclusive headphones may not work properly depending on the environment.
3. Lip-sync (audio delay) errors can occur with certain Bluetooth setups.
4. The TV and Bluetooth device may disconnect if the distance between them is too great or if there are obstacles.

If the delay continues, we recommend using a wired connection (HDMI) for improved audio performance.

Should you have any questions or need further assistance, please contact Samsung Customer Support at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. LiveChat agents are also available through the ‘Support’ link on our website.
